10) EXTENSION CABLE SELECTION
The machines are factory fitted with a 9 ¾ft length of cable having three conductors 16AWG
LIVE, NEUTRAL and EARTH. If it becomes necessary to fit an extension cable from the power
source, care must be taken in using a cable of adequate capacity. Failure to do so will result in a
loss of traction by the magnet and a reduction of power from the motor.
Assuming a normal AC supply of the correct voltage, it is recommended that the following
extension lengths shall not be exceeded:
For 120v supply:
11 ½ft of 3 core x 16AWG
ALWAYS DISCONNECT THE MACHINE FROM THE POWER SOURCE BEFORE CHANGING CUTTERS.
